This repo contains a set of runnable examples of AI workflows and agents, using Durable Execution and Orchestration via Restate (Github)
The goal is to show how you can easily add production-grade resilience, state persistence, retries, suspend/resume, human-in-the-loop, and observability to agentic workflows. So you can ship agents that stay alive and consistent without sprinkling retry-code everywhere and without building heavyweight infra yourself.
The Restate approach works independent of specific SDKs but integrates easily with popular SDKs, like the Vercel AI SDK, the OpenAI Agent SDK, and Google ADK. You can also use without any Agent SDK (roll your own loop) or for more traditional workflows.
| Use Case | What it solves |
|---|---|
| Durable Execution | Crash-safe model and tool calls, idempotent retries, agents that resume at the last successful step. |
| Detailed Observability | Auto-captured trace of every step, retry, and message for easy debugging and auditing. |
| Human-in-the-loop & long waits | Suspend while waiting for user approval or slow jobs; pay for compute, not wall-clock time. |
| Stateful sessions / memory | Keep multi-turn conversations and other state isolated and consistent. |
| Multi-agent orchestration | Reliable RPC, queuing, and scheduling between agents running in separate processes. |
